This specification, aided by the accompanying drawing, discloses certainnew and useful improvements in features of construction as well as themeans and mode of operation of container valves of the characterdisclosed in the co-pending application for Container valves, filed June21, 1937, Serial Number 149,353.

The present invention is related to a container valve in which the valveaperture closure is engaged permanently to the valve for continuousoperative employment thereon thereby serving to eliminate theobjectionable performance of screwing the aperture closure on and offthe container,

The primary object therefore of the herein described and illustratedinvention isto simplify the construction of container valves in such anovel, economical and operatively efiicient manner, that all of thedifficulties and incapacities encountered in prior art structures areovercome.

To such ends, briefly summarized, this invention is of and for acontainer valve characterized by features providing:-

A container valve closure characterized by the I feature of havingoscillatory movement on a pivot axis and journal bearings of novelconstruction.

A container valve characterized by the feature of having a closureprovided with elongated journal bearings.

' A container valve characterized by the feature of having a closureprovided with journal bearings interrupted by off-set portions formingindentations therewithin.

A container valve characterized by the feature of having a closureoperative on a support provided with hearing axes of rectangular form.

A container valve characterized by the feature that the closure portionthereof can be securely locked when moved in one direction and capableof oscillatory movement when moved into a position in opposite directionto that of the first mentioned direction and vice versa in accordancewith the desire to lock or unlock the closure.

A container valve characterized by the feature of having a closuresupport integrally unitary in structure.

A container valve characterized by the feature that the journal bearingaxes of the closure support is rectangular in form.

A container valve characterized by the feature that all of its partsconstituting the structure of the valve are so designed and constructedthat they are capable of production by means of dieforming processes,thus insuring economical production and accurate duplication andindefinite reproduction.

For the purpose more clearly to understand the expressed objects, andother attending objects,

the following description is given, and by aid 01"' the accompanyingdrawing, it is discernible:

The parts constituting this container valve are herein designatednumerically, and in the order of which 12 identifies a fragmentaryportion of a container herein denominated a collapsible tube.

The collapsible tube [2 is provided with a discharge end having anopening is surrounded by an embossment l4. On the surface l5 of theembossment there is seated a die-formed metallic slug l6 designed toprovide a support. The slug i6 is provided with an aperture ll locatedwithin a portion of the body of the slug which portion is die-formed insuch a way that an offset surface providing a depression 3 is formedwithin the slug, and an expressed projection I9 is formed on an oppositesurface of the slug. Arranged on the slug I6, and integral therewith,are lateral projecting portions 20 and 2| forming limbs providingjournal axes 22 and 23, and midway the end of the limbs 20 and 2|, andwithin the body of the slug IS, an opening is made to provide anindentation 2t.

Within the aperture I'lof the slug, formed to provide a support, atubular formed body 25 having an enlargement providing a rim 26, isarranged in assembly with the rim 26 of the tubular formed body 25seated within the depressed portion I8. Thus assembled the extendingportion of the tubularly formed body 25 is pressed within the opening l3of the discharge end of the collapsible tube, and in order to secure theassembly to the tube, a marginal end 21 of the body 25 is crimped orotherwise spun over in such a way as to form a flange and by means ofwhich the assembly is secured to the tube.

There is also included in this valve assembly, a member part providingan aperture closure 28. The closure 28 having rectangularly bent flaps29 and 30 and within the flaps, journal bearings 3| and 32 are provided,and so formed that oliset indentations 33 and 34 interrupt the circularcontour of the journals 3| and 32. Formed on the body of the closure 28is a tang 35,--the tang having a resiliently yielding capacity, the tang35 being bent to provide a deflected end 36.

At a suitable position on the body of the closure 28, angularly benttabs 31 and 38 are provided; the tab 31 being arranged to provide fingermanipulating means for the closure 28, and

out portion of the tab 31, is formed to provide locking means effectedby theclaw 39.

The closure thus described is arranged in assembly on the support l6,and the manner of its assembly thereon is effected, firstly: by enteringone of the journal axes of the support 16 into one of the journalbearings of the closure, more conveniently accomplished however when theclosure is tilted at an angle; secondly: then the other journal bearingof the closure, being aligned with the respective axis of the supportI6, is pressed in a manner to permit the resiliently yielding tang 35 tospring into the indentation 24 with the bent end 36 arranged operativelytherein, where- 'by the closure 28 is then so arranged in assembly onthe support that no displacement of the closure is possible.

In the drawing the view Fig. 1 shows the closure 28 in locked engagementon the valve, and in the view Fig. 2 of the drawing, the closure isillustrated as in an unlocked position to permit oscillatory movement ofthe closure 28 in the direction of the arrow line, dotted.

To arrange the closure 28 in locked engagement as shown in Fig. 1, it isnecessary to exert sufiicient finger pressure on the tab 31, in thedirection indicated by the arrow, thereby slidably pressing the closureinto a position which permits the axes 22 and 23 to enter theindentations 33 and 34 of the closure journals, and, at this instance,the claw 39 will have engaged beneath the surface I6 of the closuresupport, thereby effecting a locked engagement of the closure 28 on itsaxis as well as by a latching engagement; in

.other words, the closure is locked by two independent locking means. 7

The unlocking of the closure is the reverse operation of locking theclosure, and the unlocking is brought about by sliding the closure(indicated .by the arrow in the view Fig. 2) in the direction which thearrow indicates when finger pressure is exerted upon the tab 31; theclosure is then brought to a position in which the axes 22 and 23 enterinto bearing contact with the journal bearings 32 and 33 of the closure,at the instance of which, the closure is capable of oscillatory movementin the direction indicated by the dotted lines of the arrow.

It is essential that the closure of the valve be free from leakage, andin order to provide a seal tight joint between the closure and thedischarge aperture, a fabricated gasket 40 is employed, and arranged inassembly on the valve, by seating the gasket into the depression l8, inwhich position the gasket serves to prevent leakage by forming aseal-tight joint between the surfaces with which it is in contact.

In conclusion, reference is made to the embossment l4 surrounding theaperture I3 of the tube I2. The embossment I4 is of very limited heightand so designed and proportioned that a very scant quantity of materialis employed in its formation, in consequence of which, an appreciablesaving is effected in cost of material over structures requiring alarger volume of material.

Having thus described the invention, it is obvious that there isprovided a container valve of the character described and possessed ofthe advantageous features hereinbefore enumerated as desirable. It istherefore to be understood that the container valve is susceptible ofmodification in its form, proportions, detailed construction andarrangement of parts without departing from the principle involved orsacrificing any of its advantages.

The invention has been described in language more or less specific as tostructural features. It is to be understood, however, that the inventionis not limited to the specific details shown, but that the means andconstruction herein disclosed comprises the preferred form of severalmodes of 1 putting the invention into effect and the invention thereforeis claimed in any of its forms or modifications within. the legitimateand valid scope of the appended claims.
